My case is downloading a WiiU WUD file and converting it to a WUX (compressed/stripped) file saving space.

But the same would apply to many similar Rom files like PSP ISOs to CSO, or stripping 3DS roms or even repacking ZIPs to 7Z....

I am hopeless at scripts and batch files but my SABnzbd is running on a Docker on unRAID so probably need script to be Linux friendly. I feel brave enough to compile the Wudcompress source to make an executable
